2. Feed the dry metal into the mill, applying snug (but not overpowering) pressure on rollers. 3. After rolling metal through the mill, flip the piece end to end before you roll it through again. You will get a more even roll. 4. Before passing the metal through the rollers, lower the rollers until you again have a snug fit (as in step 2). 5.
